Product Description

The HKS 12001-KT004 GT2 S/C System Pro is a complete forced induction upgrade designed specifically for the Toyota 86 and Subaru BRZ with the FA20 2.0L engine (model years 2013-2021 confirmed). This supercharger system replaces the factory naturally aspirated setup with a high-efficiency GT2 roots-style blower and dedicated intercooler system, significantly increasing engine output and torque across the rev range compared to stock.

Built by HKS with precision engineering and high-quality components, the GT2 S/C System Pro features everything needed for installation, including brackets, pulleys, hoses, and necessary hardware. Designed to work with standard pump gas (91 RON), it delivers an accessible power upgrade while retaining drivability. Optional upgrades such as pulley kits, upgraded fuel pump, and injectors can be added to further increase output, especially on E85 fuel. Installation typically requires ECU recalibration to optimize fuel and ignition settings for the forced induction setup.
